Types of Blood

 Blood is a specific body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including the transfer of oxygen and nutrients to the lungs and tissues. Making blood clots to prevent blood clots. The blood that passes through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55% plasma and 45% blood cells. About 7 to 8% of your body weight is blood. An average-sized man’s body contains about 12 pints of blood, and an average-sized woman’s body contains about nine pints.



What are the types of blood cells?

Following types of blood cells

1. Red Blood Cells

 Blood appears red due to the large number of red blood cells, which derive their color from hemoglobin. The percentage of total blood volume made up of red blood cells is called hematocrit and is a general measure of the level of red blood cells.

2. White Blood Cells 

White blood cells protect the body from infection. They are much smaller in number than the red blood cells, which make up about 1% of your blood. The most common type of white blood cell is the neutrophil, which is an “immediate reaction” cell and accounts for 55 to 70% of the total white blood cell count.

3. Plasma

The liquid component of blood is called plasma, a mixture of water, sugar, fat, protein and salts. The essential function is to move blood cells throughout your body, as well as nutrients, waste products, antibodies, clotting proteins, hormones such as chemical messengers, and proteins that help maintain the body’s fluid balance.

 4. Platelets:

Unlike red and white blood cells, platelets are not actually cells but small fragments of cells. Platelets accumulate at the site of injury, clinging to the lining of the injured blood vessel, and forming a platform to aid in the process of blood clotting (or clotting) on ​​which blood can clot. This results in fibrin clots, which cover the wound and prevent blood from flowing out. Fiber also forms the initial support on which new tissues are formed, thus promoting healing. Excessive platelet counts can cause unnecessary clotting, which can lead to stroke and heart attack. Treatments are available to help prevent these potentially fatal events. On the contrary, it can cause less bleeding than normal.

How Does Blood Travel in the Body

The circulatory system is made up of blood vessels that carry blood to and from the heart.

Two types of blood carry blood in our body

  1. The arteries carry oxygenated blood (blood that receives oxygen from the lungs) from the heart to the rest of the body.

2. The blood then travels through the veins back to the heart and lungs, so it can get more oxygen to send back to the body through the arteries.

The eyes detect light and convert it into electrochemical ampoules in neurons. The human eye, a special sensory organ capable of receiving visual images, is then transmitted to the brain . Structure of eyes The structure and function of the eyes are complex. Each eye constantly adjusts the amount of light that it receives, focuses on near and far objects, and constantly produces images that are instantly transmitted to the brain . 1. Choroid A layer of blood vessels that covers the back of the eye and lies between the retina (the sensitive layer of inner light) and the sclera (outer white eye wall). 2. Ciliary Body The structure that consists of muscles and is located behind the iris, which focuses on the lens. 3.
